Here is my view on the offsides call on UNC when they recovered the ball on the onsides kick. There wasn't an offsides. UNC recovered the ball and should have had another chance with under a minute to go. Why the ref threw the flag, I have no idea, it is pure speculation. That officially means that a ref can throw a random flag in a game changing moment and it's non reviewable. I'd like to know why can't they review the play, decide that there was no one offsides and pick up the flag.
It will be interesting in the next few days to hear the official explanation.
